I've done little to no
research on this fish, since it has not been readily available. You can check
out various fishing web sites under the African Tiger Fish or genus name Hydrocynus
and that should give you a lot of native habitat information.

OPEFE was recently sent 5
preserved African Tiger Fish juveniles. On March 22, 2000 OPEFE secured 2 live
specimens of Hydrocynus vittatus. Most of these were sent to Oregon State
University where Dr. Douglas Markle will be using them for his neo-tropical
division students. The fish measured about 5-6 inches each and all were
positively identified by Dr. Markle's student as H. vittatus.

Hydrocynus (or fish dogs, or fish tigers) are known strict
ichthyophagous for their promptness and their voracity. All the fish belonging
to this kind appreciably look the same and only an attentive examination makes
it possible to differentiate them. They have a torpedo form, which they use to
their advantage of nourishing itself, since they continuously chase their prey.
The fish are generally silver plated and brilliant. The scales are marked with a
dark spot, thus forming especially visible parallel stripes above the side line.
According to certain species', these lines are more or less dark. The dorsal fin
is inserted into the same level as the ventral fins or a little ahead. The mouth
is armed with only one series of teeth, very developed and sharp, on each jaw.
The eye is almost entirely covered with a fat eyelid.
